C. Geomagnetic Activity Summary
THE GEOMAGNETIC FIELD RANGED FROM UNSETTLED TO MAJOR STORM LEVELS. A SHOCK WAS OBSERVED BY THE ACE SPACECRAFT AROUND 06/1600UT. THE ASSOCIATED SUDDEN IMPULSE WAS OBSERVED AT 1640UT (37NT AS OBSERVED AT SAN JUAN) AND THE FIELD HAS BEEN AT MAJOR STORM LEVELS SINCE THAT TIME. THERE WERE MAGNETOPAUSE CROSSINGS OBSERVED ON BOTH GOES 8 AND GOES 10 STARTING AROUND 1800UT. THIS DISTURBANCE IS MOST LIKELY THE CONSEQUENCE OF THE HALO CME OBSERVED FOLLOWING THE C9/2F FLARE AT 04/1541UT. THE SATELLITE PROTON EVENT WHICH BEGAN AT 04/2055UT, ENDED TODAY AT 0155UT.
